The twisted or resupinate flowers of Brachycorythis pubescens grow in a dense, cylindrical spike.
The median sepal forms the hood at the top of the flower, flanked closely by the two lateral petals. The two broadly oblique-shaped lateral sepals spread or curve in beside the hood, all protective over the column.
The lip is broad and either flexed down or nearly horizontal, curving in and forming three lobes at its tip, the central one of which is smaller. Yellow colouring with a few scattered dark spots occur at the lip base below the column. A small sac, not quite a spur, is also present at the base of the lip.
The column of the flower in its centre is erect, the caudicles short. Caudicles are stalk-like structures in the male flower component. They are derived from anther tissue, attached to the viscidium, a sticky part grown from the female stigma, serving to attach to pollinators. The reproductive parts of both genders reside in the column, separated somewhat by a divider, the rostellum.
Flowering happens from mid-spring to early summer (Lowrey and Wright, 1987; Pooley, 1998).
